I have seen many people from other countries say things like, "I would not want to live in the U.S if I were poor." 

I grew up with a single parent and two half-brothers in the United States between 1993 and 2012. I live in a pretty average state in all ways, Pennsylvania. My mother's income was at or below the 10th percentile of all Americans. 

This is what life was like growing up poor: 

My mother got $600 /month in food stamps at times. She got so much that she would sell what she couldn't spend to her friends for 90 cents to the dollar. She'd use that money to pay bills and buy cigarettes.  

We lived in subsidized housing, my mother's rent was $100-300 per month depending on how much she made. This was for a nice, newly built, three bedroom apartment. 

My mother received $200 in child support from my father per month, and sporadically $100 per month for the father of my half brothers. 

All of our health insurance was subsidized. I got hit by a car when I was ten years old. The bill came in for $3,000. We paid zero dollars of that three-thousand. Copays were either zero dollars or two dollars. 

My mother owned a car at all times, we had cable, electricity, water, internet, video game consoles, computers and all necessities and plenty of other luxuries. 

Every year she would receive $2,000 - $4,000 back in an income tax refund. She essentially didn't pay any income tax. 

My mother would spend something like $1,500 - $2,000 on cigarettes per year. 

I was a good student in school. I had a 3.9 GPA when I graduated high school. There was no incentive for my mother(or father) to save money for college because they figured the government would pay for it. My last year of high school, even though it was a mediocre public school, I spent my time applying to a dozen colleges. I got into a private university that ranks in the top 23rd in the United States, my financial aid reward from the university was 4/5ths of the tuition, government grants and loans covered the rest of my expenses. I chose to remove loans from the equation by working part time jobs. 

I never was without food, housing (except living in a domestic violence shelter for 6 months), resources for school, medical attention, clothes, etc. 

So what are the poor missing out on in the U.S that makes people from other countries so scared of being poor here? I find the poor live a life of luxury to be honest. The only thing I feel I missed out on was a real, cohesive, and intelligent upbringing. But I figured that out for myself. 

Living in the gettho or poor area in the US and working your entire day. Its not so mch money related but culture

The middle class and rich work just as many if not more hours than the poor from my experience. "Living in a ghetto" is such a ridiculous stereotype. Most "ghettos" are not how they are advertised on television. I only saw ghettos of those type when I would visit my dad who lives in New York City. 

While there were times my mother had two jobs, if she were responsible with her money she wouldn't have to do that. Of course, it was the same decisions that kept her poor in the first place that lead to this. She should not be rewarded for these decisions with even more exhorbiant benefits than she already received. 

I think living in US is far much better then living in war area like Gaza, Syria, Ethiopia, or even North Korea, even if you are poor. lol

There are millions of children starving, so starvation is one thing. Being forced to live in lower income areas, the likelihood of drugs and violence are dramatically increased, which makes it much more likely for poor people to become criminals trying to find a way out. Also, many adolescents have to get a job to support their family, which can affect their grades at school, with many dropping out (for example, my uncle lived in a poor family of drug addicts, which led to him having to work to afford living, and as a result had to drop out of high school).

Not buying videogames and change you apple products every year

Where are "millions of children starving"? How many children died of malnutrition in the U.S last year?  I never knew a single starving child in my life who lived in the U.S. If you are poor enough you automatically qualify for food stamps and free breakfasts and lunches at school. And I had many friends who were just as poor as I was. 

Who is being forced to live in lower income areas? If my mother decided to finish high school and get a decent enough job she wouldn't have to live in subsidized housing. But subsidized housing wasn't bad anyway. Living in a "low income area" is only bad for people who are scared of the poor. We ended up living in a pretty nice middle class small city (13,000 people) during my high school years, anyway. 

I did not have to get a job during high school. Like I said, my mother had many benefits with minimal expenses and took a second job when she had to. 

The context you described seems to be only the case for people who live in inner-cities that are designed particularly to "help" the poor.  

Well, I live in NYC, and those ghettos kind of suck.  And they typically have horrible schools, so your chances of getting out of them are diminished.  I taught in a school where a significant (maybe 10-20%) of the students lived in shelters.

Where exactly did you grow up in Pennsylvania?  Philadelphia?  Cause there are some really shitty places to live there.  If you were in the suburbs or smaller cities in Pennsylvania, your experience may not be the same as those who live in larger cities. 

Btw, not sure why you brought up child support.  Nothing to do with poverty.  

I'm assuming that people have higher standards in the United States for been poor compared to a lot of other countries ?

Not a whole lot sucks about been poor in the US when what you described was living like a king in the eyes of many 3rd world countries or shitholes like Somalia ...

I grew up in the Scranton-Wilkes-Barre-Hazleton metropolitan area. While murders and violent crime were similar to other small metropolitan areas, in my county drugs and alcohol were huge, as it is a major route for the drug trade between Philadelphia and New York City. Meth labs were busted quite often. The court system was also very corrupt (see: kids for cash scandal.)

My high school was ranked 413/500 schools in Pennsylvania in 2012, when I graduated. While it was no inner-city school, it wasn't that great of an education either.
